Hello,
I followed with success a tutorial with QVTo. But my objectives is UML
to UML transformation with UML Profiles. I saw previous messages on
Profiles, so I will get there eventually and get back to these.
Meanwhile, the tutorial I used is transforming models produces with
Ecore files From observation of a Papyrus XMI file, the models looks
similar, but I am blocking on a first issues and I cannot find the
solution in the past M2M messages. By the way, Google has a hard time
with the eclipse forum references, I can rely on the Google cache, but
is this a temporary problem ?
Back to my issue, I have
modeltype umlMM uses 'http://www.eclipse.org/uml2/3.0.0/UML';
transformation CIMTransformation(in umlIn : umlMM, out umlOut : umlMM);
main() {
-- umlIn.rootObjects()[umlIn::Package] -> map ...
}
Q1 - Going to [Operational QVT Project] > [Properties] > [QVT Settings]
> [Metamodel mappings], I cannot find the way of adding a local
reference to the uml metamodel. How can I ?
Q2 - I guess this problem is related to Q1. I do not get Completion in
(Ctrl-space) the transformation file ?
Q3 - Will I have to convert in some way the uml model file (produced
with Papyrus) with a conform ecore file, or it is a valid ecore
file ?
I can read the model with the sample Ecore editor, but I do not
want to assume it is valid.
Regards.

Hi Tex Iano

Hm, I must be in the wrong menu settings...
Can you indicate me a page from the web, where I can follow
the procedure to do so, or the menu you are talking about ?
Are you refering to the menu listed in my question Q1 ?
Every attempts to insert different flavor of platform:...
failed. What kind of entries should I insert in the
Metamodel mappings source and target uri fields ?
> So install the UML2 package for
I presume it is already there, since I have Papyrus (UML Modeler)
and QVTo installed. I did though, since you mentionned it installed
the 2 following packages:
+ EMF Compare UML2 Integration
+ UML2 Extender SDK
From Help>Install new software, I cannot find anything else related to
UML2. From the Eclipse Plug-ins list, I seem to have all UML2 related
software, UML2 Model Search Ui, UML2 UML Editor, ...
Still, cannot have any completion (and this indicate me I did not
configured my project correctly) !
Any other hints ?
Thanks in advance.

As an add-on to this discussion, from the wiki.eclipse.org/MDT/OCL/FAQ,
I get that ecore is a standalone metamodel that can define itself, and
that ecore can be used to express a UML metamodel. Furthermore, it
seems that UML is already delivered with QVTo. Hm... I still do not get
where the java PackageToPackage method is being defined. I verified
that that ecore::EPackage exist, both should use this definition for
my uml to uml transformation ?
Therefore, what is the equivalent PackageToPackage() in the ecore world ?
Finally, if I rely on ecore mm, I can imagine that I will miss some uml
concepts along the way, that those defined in uml but not in ecore.
Am I right ?
Regards.

Hi
Your multiple messages seem to be getting increasingly confused.
I suggest a little more thought before pressing the send button,
otherwise I may start treating your messages as spam.
PackageToPackage is of course a mapping between two classes, so if you
use some other metamodel the parameter types will change.
Ecore corresponds to EMOF which is a simplified form of UML. If you
don't like the simplifications don't simplify.
An EMF mapping might be called EPackageToEPackage.
